ROLAND A. BEATTY, OF NEW YORK, N. Y.

MAGAZINE-HAMMER.

Application filed May 18, 1918.

To all whom it may concern Be it known that I, ROLAND A. BEATTY, a citizen of the United States, residing at Bronx, in the county of Bronx and State of New York, have invented certain new and useful Improvements in Magazine-Hammers, of which the following is a specification.

This invention relates to nail-driving implements, and more especially to those which are provided with a magazine; and the object of the same is to produce an implement of this kind in which a number of nails or tacks of a variety of sizes are fed to the point of use and delivered thereby so as to be placed by the user and then sunk in place.

A further object is to provide means whereby nails or tacks of a variety of sizes may be selectively fed or supplied to the point of use.

Another object is to provide means whereby the magazine can be charged from time to time.

Yet other objects will appear in the following specification and claims, and reference is made to the drawings herewith and in which Figure 1 is a side elevation and Fig. 2 a central longitudinal section of this hammer complete,

Figs. 3 and 4 are enlarged cross sections on the lines 33 and 4l-l of Fig. 2,

Fig. 5 is an enlarged sectional detail showing the gate mechanism, taken on the line 55 of Fig. 2, and

Fig. 6 is an enlarged perspective detail showing the nail-holding mechanism.

The handle 1 of this hammer is a hollow cylinder, preferably of metal and preferably cast integral with the right-angular head 2 thereof, the same having a driving face 3 at its lower end and a naildrawing claw l at its upper end as usual. lVithin the handle near the head is fastened a transverse partition 5 in whose center is rotatably mounted a trunnion 6 and one end of a shaft 7 constituting the axis of a magazine, the balance of the same consisting of a group of tubes 8 externally of the same size but having bores of different size as best seen in Fig. 3, so that in effect the magazine contains plurality of chambers constituting small magazines for nails, brads, or tacks having heads of different sizes. The trunnion 9 at the rear end of the shaft 7 may be rotatably mounted in a socket at the center of a cap 10 which Specification of Letters Patent.

Serial No. 235,285.

screws on the rear end of the handle as shown at 11 and which, when unscrewed and removed, gives access to the open rear ends of the small tubes so that any one which may be empty may be recharged. From said trunnion 9 projects a pin 12 adapted to be set into any one of a series of notches 13 with which the rear end of the handle is provided, so as to hold the magazine in any position to which it has been adjusted, for a purpose yet to appear. Through the partition 5 at one side of the trunnion 6 is an opening. and within this opening is mounted the inlet end of a main or feed tube 15 which leads thence forward, makes a bend downward as seen in 2, and extends along the outer side of the hollow head 2, opening through the lower end of the same at a point just forward of the driving face The notches 13 are so disposed in the rear end of the handle that, according as the point 12 is set in them, one or the other of the tubes 8 are brought into registry with the inlet end of the feed tube 15; and accordingly the operator may select which magazine tube he is to aline with the feed tube, and therefore which size or shape of nails, etc. is to be supplied. Meanwhile all the other tubes have their front ends closed by the partition 5, while their rear ends are of'course closed by the cap 10 as long as the latter remains in position. I do not wish to be limited, however, to tubes 8 having different size bores as shown in Fig. 3. If we should assume, for instance, that this device is to be employed by a lather who is to drive a large number of nails which are all of one size and shape, it might be of advantage for him to have a magazine with a plurality of tubes 8 which are all alike and the bore thereof capable of receiving the head of lathing tacks or nails as will be clear. hen now he has exhausted the charge within one tube, he has but to remove the cap and turn the point 12 to another notch 13 so as to bring another tube into registry with the main tube, and then to continue the operation as before.

Feed mechanism must be provided within this main or feed tube so as to deliver nails or tacks one by one to the point of use, and this mechanism is best shown in Figs. 2 and Said feed tube is interrupted at the point 20, and within this interruption stands an upright ring constituting a bridge 21. Slida ly mounted over this bridge are two gates 22 and 23, the former having a hole in its body through which the latter projects as best seen in Fig. 2. These gates stand substantially at right angles to each other and in planes which cross each other as shown in Fig. 5, and their upper ends are respectively pivoted at 24 and 25 on pins connected with a rod 26 which is mounted for reciprocation through the partition 5 and has a knob or handle 27 at its rear end. The latter is turned out through a slot 28 in the side of the main handle, and a spring 29 bears it normally forward. In this position the gate 23 stands raised and the gate 22 closed as seen in Fig. 5. When now the handle is inclined with the head 2 downward a little, a nail or tack passes out of the tube 15 under the gate 23, through the bridge 21, and against the gate 22; and when the operator puts his finger over the knob 27 and retracts the rod 26 so that the gates assume the opposite position from that illustrated in Fig. 5, the nail in question may pass under the gate 22 which now restrains it, and continue along the tube to the point of use. When the operator removes his finger from the knob 27, the spring 29 restores the parts to the position shown in i Fig. 5, and another nail or tack is released,

ready to be supplied at the next impulse.

The pin 25 on which the gate 23 is pivoted is really the downturned end of the rod .26, and it is continued downward as at 35'into a fork 30 which projects through a slot 31 in the feed tube just above its outlet end through the hole in the driving face 3. Close above the fork stands a plate 32 projecting through another slot 33 in said tube,

- this plate being carried at the lower end of another rod 36 which rises throughout the hollow head 2, makes a right angular bend as shown in Fig. 2, and is carried to the rear through the partition 5 and preferably along the lower side of the handle. At its rear end it is turned outward as at 36 and carrles a knob 3? beyond a slot 38 1n the handle, a spring 39 bearing this turned out end normally forward the same as with the uppermost knob and spring already described. It is seen that the two rods described reciprocate within the handle and are entirely independent of the rotary movement of the magazine, and also that they do not interfere with its withdrawal and reinsertion as described above.

The operation of this device is as fol lows :-Assuming that the magazine has been set so that a certain size of tacks is fed. Each tack passes under the gate mechanism already described and in the manner set forth above, and travels over the bend in the feed tube 15 until its point rests upon the plate 32 as shown in Fig. 2. When the lower knob 37 is retracted the plate is drawn out from under the tack, so that the latter drops with its point through the fork 3O the driving face 3. The point of the tackmay now be seated in the wood by a gentle blow, in a manner well understood by carpenters and those familiar with tools of this character. Immediately after having seated this tack or nail, the operator retracts the other knob 27, with the result that the fork 30 is withdrawn from beneath the head of this tack and it is released. This he can do almost automatically with his thumb at the top when he makes the strokewhich seats the tack, and therefore as he withdraws or retracts the hammer for a blow on its driving face 3, he leaves the tack sticking in the wood, and the next action is to sink it by a proper driving action as usual. Meanwhile it is quite possible that he may become sufficiently expert to cause the movement of the hammer by a swinging action to project another tack from the tube 8 through the gate mechanism shown in Fig. 5, which mechanism is naturally and automatically actuated as he retracts the upper knob 27 in withdrawing the plate. In this way a large number of tacks or nails can be rapidly driven, one blow sea-ting the tack and the next sinking it as will beunderstood.

The foregoing description and the drawings have reference to what may be considered the preferred, or approved form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, materials, dimensions, et cetera, as may prove expedient and fall within the scope of the appended claims. 1
